Royal Dairy Royal City, Washington, USA
The Problem

Royal Dairy is a large dairy built in 2001 with 15,000 head and 7,000 milking cows. The Allred family strives to be progressive in every area of operation and have successfully positioned Royal Dairy as a leader in sustainability in Washington State. On the search for processes that can improve sustainability, Royal Dairy sought technologies that are more effective in capitalizing upon the essential nutrients of dairy flush effluent to convert waste into a beneficial byproduct. 

 

The BioFiltro Solution

Royal Dairy executed a phased implementation in which BioFiltro first designed and installed a 5,000 GPD system to enable the client to test not only its performance with their lagoon water, but also system viability for the cold winter. After two years of operation, the pilot has averaged 93% removal of Total Nitrogen, 97% removal of Total Suspended Solids, and 90% removal of Total Phosphorus. 

This August, BioFiltro and Austin Allred will commission what will be, to date, the largest BIDA® System in the United States. The 200,000 GPD facility will treat dairy flush from approximately 7,000 milk cows to enable Austin and his dairy to exceed nutrient management goals.

The Results

 

  • 97%
    Average Total Suspend Solids Removal
  • 29°F
    Average Exterior Winter Temperature
  • 93%
    Average Total Nitrogen Removal
This is the first system that we found that could provide an economical and efficient solution capable of cleaning our green water. The simplicity of using worms and biology is brilliant.
